Dentigerous cysts in horses: A retrospective study
Background
Dentigerous cysts are well-known congenital defects in horses, and the literature on this condition is extensive. Recently, a third type of dentigerous cyst, associated with an exostosis arising from the temporal bone, has been described. Today, computed tomography (CT) is often available and provides detailed information about the exact location and extent of dentigerous cysts, allowing for the description of new findings.
Study design
This is a case series outlining the clinical, radiographic and computed tomographic features of dentigerous cysts in seven horses presented to the Equine Clinic at the Vetsuisse Faculty, University of Zurich, Switzerland.
Objectives
The aim of this case series was to describe the radiographic and computed tomographic findings, and the occurrence of exostoses arising from the temporal bone, in horses with dentigerous cysts.
Methods
The medical records of the Equine Hospital at the University of Zurich were reviewed for horses admitted with dentigerous cysts between 2007 and 2023. Data collected and analysed included patient signalment, clinical history, clinical signs and their duration prior to referral, diagnostic imaging results, treatment and outcomes.
Results
The most common location for the cysts was the base of the ear, although in one case, the maxillary sinus was involved. Of the seven cases, four were Icelandic horses. CT proved superior to standard radiography for determining the extent and precise location of the cysts, as well as for identifying dental material and exostoses in the temporal region. CT also facilitated detailed surgical planning. All cysts were surgically removed with good long-term outcomes.
Main limitations
Overall, the incidence of dentigerous cysts in horses was low. The relatively high occurrence of dentigerous cysts in Icelandic horses in this study is an interesting finding, though the small sample size calls for further research.
Conclusions
Two of the cases in this series were similar to a recently described variant of a ‘temporal dentigerous cyst associated with an exostosis in the temporal region’ and were closely connected to the bony structure and draining tract.
期刊介绍：
Equine Veterinary Education (EVE) is the official journal of post-graduate education of both the British Equine Veterinary Association (BEVA) and the American Association of Equine Practitioners (AAEP).
Equine Veterinary Education is a monthly, peer-reviewed, subscription-based journal, integrating clinical research papers, review articles and case reports from international sources, covering all aspects of medicine and surgery relating to equids. These papers facilitate the dissemination and implementation of new ideas and techniques relating to clinical veterinary practice, with the ultimate aim of promoting best practice. New developments are placed in perspective, encompassing new concepts and peer commentary. The target audience is veterinarians primarily engaged in the practise of equine medicine and surgery. The educational value of a submitted article is one of the most important criteria that are assessed when deciding whether to accept it for publication. Articles do not necessarily need to contain original or novel information but we welcome submission of this material. The educational value of an article may relate to articles published with it (e.g. a Case Report may not have direct educational value but an associated Clinical Commentary or Review Article published alongside it will enhance the educational value).
